To all whom it may concern: I ther object'swhich will appear as thenature Be it known that I, CHRISTOPHER Jennof my invention is more fullydisclosed, I LAKE, (formerly JOHN CHRISTOPHER Lana) have invented anovel valve or regulator a. citizen of the United States, and a resiioneembodiment of which, as adapted to 55 dent of Bridgeport, in thecounty of Fairl two fluids, will be described by reference to field andState of Connecticut,'have invented the annexed drawing in which,certain new and useful Improvements in Figure 1 represents an outsideview of my v Mixing and Regulating Valves, of which improved valve, Fig.2 is a sectional view the following is a specification. l showing itsinternal construction.

I In this arrangement the stem 9 1sprovided with the inion 16 which is engaged b'y therack 19 attached tothe stem 18 of the automatic governorl'i'. When a governor is thus usedall the passages in the mixing device are normally open, especially whenthe engine is at rest and are only partly closed by the action of thegovernor. The hand wheel 13 is therefore retained to afiord a positivemeans of cut-off and means may be provided if desired for disconnectmgthe governor when the valve is operated by means of the hand Wheel.

The operation of my device is as follows; Referring to Figs. 1 and 2,when starting the mixer the stem 9 is withdrawn by turnto open thechamber a to the outlet 3. The two fluids are then admitted from thepipes 2 through the aux iliary chambers 5 by turning the wheels 12 untilthe desired mixture is obtained. llaving then secured the desired fluidmixture, the quantity of flow is controlled or entirely out olf byturning the wheel 13 of the stem 9. The supply of the mixture can thusbe conveniently controlled without the inconvcnience of adjusting theproportions oi.

the mixture every time it is used and for variable loads. Referring toFigs. 3 and at the mixer is started by turning the wheel 13, the handwheels 12 having been previously adjusted for the proper mixture. Whenthe peed of the engine goes above normal, the governor balls swingoutwardly and depress the stem 18 and the rack 19 attached thereto. Therack 19 engaging with the pinion 16 on the stein'9 rotates it in theproper direction for closing the combined passa es, thus diminishing thefuel supply and tiereby reducing the speed of the engine. The efi'ect ofthis reduction of speed if carried below the normal is to cause thegovernor to act in the contrary manner, thereby opening wider thecombined passage and admitting a larger supply of fuel.

Having now described one of the forms in which my invention may beembodied, what I claim and desire to secure by Letters Patent is:

1. In a mixing valve, the combination of a main chamber provided with aplurality of inlets and a single outlet forming openingstherein, inletchambers communicating therewith, means for controlling the admission offluids from said chambers to the main chamber, and a single means in themain chamber adapted to open and close all the openings therein.

2. In a mixing valve, the combination of a main chamber provided with aplurality of inlets and a single outlet forming opcnings therein, inletchambers communicating therewith, independent means for controlling theadmission of fluids from said inlet chambers to the main chamber, and asingle means in the main chamber adapted to open and close all theopenings therein.
